Termoflex XF 13 mm Self-Adhesive Closed Cell Foam Insulation for Campervans & Van Conversions

Termoflex XF 13 mm is a premium self-adhesive closed cell foam insulation engineered for campervans, vans, motorhomes, boats and commercial vehicles. Manufactured from high-quality elastomeric rubber foam, it provides outstanding thermal insulation, condensation control and acoustic performance while remaining lightweight, flexible and easy to install.

With its 13 mm thickness, Termoflex XF offers significantly higher thermal performance than thinner insulation, making it the ideal choice for campervan walls, ceilings and other large body panels where maximum insulation efficiency is required.

The material features a high-strength self-adhesive backing that bonds securely to clean metal surfaces, ensuring fast installation and long-lasting adhesion even under vibration, changing temperatures and demanding road conditions.

Why Choose 13 mm Closed Cell Foam Insulation?

Metal vehicle bodies transfer heat extremely efficiently. During winter, heat escapes through the bodywork, while in summer the sun quickly heats the metal panels, increasing interior temperatures.

Installing 13 mm closed cell foam insulation creates a highly effective thermal barrier between the vehicle body and the living space. This improves year-round comfort, reduces energy consumption and helps maintain a more stable interior temperature.

The closed-cell elastomeric structure also prevents moisture absorption, making it one of the most effective materials available for preventing condensation inside campervans and motorhomes.

Key Benefits of Termoflex XF 13 mm

• 13 mm insulation thickness for excellent thermal performance.
• Strong self-adhesive backing for fast, secure installation.
• Closed cell structure resists water and moisture.
• Excellent condensation protection for metal vehicle panels.
• Low thermal conductivity improves insulation efficiency.
• High water vapour resistance protects vehicle structures.
• Flexible material conforms to curved body panels.
• Lightweight construction with minimal added vehicle weight.
• Helps reduce road and wind noise while improving thermal comfort.
• Easy to cut using a standard utility knife.
• Dust-free and fibre-free installation.
• Long service life in demanding automotive environments.

Ideal for Campervan Walls & Roof Insulation

Termoflex XF 13 mm is specifically suited to larger insulated areas where additional thermal performance is beneficial.

Typical applications include:

• Campervan wall insulation
• Campervan ceiling insulation
• Van side panels
• Motorhome body insulation
• Boat cabins
• Large interior body panels
• Commercial vehicle insulation

The additional insulation thickness provides noticeably improved performance compared to thinner products while still fitting comfortably behind most interior wall and ceiling panels.

Excellent Condensation Control

Condensation is one of the biggest challenges in any campervan conversion.

Warm humid air naturally condenses when it comes into contact with cold metal surfaces. Over time, trapped moisture may contribute to corrosion, mould and unpleasant odours.

Because Termoflex XF is installed directly onto the metal body, it creates a continuous thermal barrier that significantly reduces condensation formation while its closed-cell structure absorbs virtually no moisture.

Outstanding Thermal Performance

Termoflex XF offers excellent insulation performance thanks to its low thermal conductivity.

• 0.034 W/mK at -30°C
• 0.036 W/mK at 0°C
• 0.039 W/mK at +40°C
• 0.044 W/mK at +70°C

This combination of low thermal conductivity and increased insulation thickness makes the 13 mm version particularly suitable for four-season campervan conversions.

13 mm vs 6 mm Foam Insulation

Choosing the right insulation thickness depends on the available installation space.

6 mm insulation is ideal for confined spaces such as doors, wheel arches and structural ribs.

13 mm insulation provides substantially better thermal performance and is recommended for campervan walls, ceilings and other large body panels where maximum comfort is desired.

Many professional builders combine both thicknesses throughout a vehicle to optimise insulation while preserving interior space.

Easy Installation

1. Clean and degrease the metal surface thoroughly.
2. Measure and cut the insulation using a sharp utility knife.
3. Remove the release liner gradually.
4. Apply firm pressure across the complete surface.
5. Install adjacent pieces tightly together to minimise thermal bridges.

For optimum adhesion, installation is recommended at temperatures above +5°C.

Improved Acoustic Comfort

Although primarily designed for thermal and condensation insulation, the flexible elastomeric foam also helps absorb airborne noise.

For maximum soundproofing performance, combine Termoflex XF with butyl sound deadening sheets. The butyl layer controls panel vibration while the foam insulation provides thermal insulation and acoustic absorption.

Frequently Asked Questions

Is 13 mm insulation suitable for campervan walls?

Yes. It is one of the most popular insulation thicknesses for campervan walls and ceilings because it offers an excellent balance between thermal performance and available interior space.

Can I install it directly onto metal?

Yes. The strong self-adhesive backing is designed to bond directly to clean, dry and grease-free metal surfaces.

Does it absorb water?

No. The closed-cell structure absorbs virtually no moisture, making it highly resistant to condensation.

Does it improve sound insulation?

Yes. It helps reduce airborne noise while significantly improving thermal comfort. Best results are achieved when used together with butyl sound deadening material.

Can I combine different insulation thicknesses?

Absolutely. Many professional campervan builders use 13 mm insulation on walls and ceilings while installing 6 mm insulation in tighter areas where space is limited.
